The scale follows an even subdivision of 0.002 mm (2 µm), so that reaching half the reference depth also corresponds to half the maximum hardness value (Rockwell hardness value 50). When diamond cones are used, the Rockwell scale is .Rockwell hardness test is one of the most common indentation hardness tests, that has been developed for hardness testing. In contrast to Brinell test, the Rockwell tester measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). . Each Rockwell hardness scale .A widely used variant of the Rockwell hardness test is the superficial Rockwell test, wherein the minor load is 3 N and the major loads are 15, 30, or 45 N.Further details on the Rockwell superficial hardness scales are available in the relevant ASTM standards (ASTM 1984).The Rockwell hardness values are expressed as a combination of hardness number and a scale .
No wonder, Rockwell hardness testing scales are globally used and are the most popular ones. It is used for static hardness testing of the material.

The calculator has two modes — calculate and convert.The calculate mode is helpful if you have the indentation depth and want the Rockwell hardness number for either scale B or C. The convert mode is for converting Rockwell hardness numbers to a different scale like Brinell or Vickers.. The hardness data can not be presented in terms of a universal . Every Rockwell hardness scale is identified by a letter signifying the indenter type and the two loads used for the test. A Rockwell hardness number is a combination of the numerical hardness value and the letter for the scale preceded by the letters, HR.While the Rockwell hardness testing scale is prevalent, it is best to consider the material thickness and softness to select the most suitable scale between Rockwell B (HRB) and Rockwell C (HRC). This article compares two types of Rockwell hardness to help you find the most ideal of the two for your hardness testing and conversion needs.
Rockwell Hardness Number – Rockwell Scale. Rockwell hardness test is one of the most common indentation hardness tests, that has been developed for hardness testing. In contrast to Brinell test, the Rockwell tester measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload .Hardness Testers from Newage Testing Instruments - Quality Assured!

The test must be carried out with a specific type of scale or tester, called a Rockwell hardness scale. How It Works. The hardness test is done through a series of pressure tests. An indenting tool, typically a diamond or ball indenter, presses against the material’s surface. After a specific hold time, the load is removed, and the indent is .The test head can easily be exchanged to measure different Rockwell scales. Versitron hardness testers can have different types of drive options from the standard level actuated drive, pneumatic drive or electric drive. Electric and pneumatic drives can be controlled with either a pushbutton or footswitch.Scale C (carbide) testers are used for testing cemented carbides in the Rockwell A Scale, where tolerances of ± 0.20 of a Rockwell Hardness point are required. A specially selected “A” Brale penetrator is used to measure the hardness of cemented carbides in accordance with ASTM B 294 and the Cemented Carbide Producer’s Association (CCPA).ix. HRK – The final scale in the Rockwell series of tests, Scale K administers 150 kgf to a steel spherical indenter. This test is frequently applied to materials like plastic, tin, and alloy.
